Read the novels on this thread: https://forum.novelupdates.com/threads/world-hopping-with-straight-mc.84810/ Now I want more similar things whether web novel, original, manga, or fan fiction. I just want some fluff with a devoted and nice male MC POV. It doesn't even need to be world hopping. Anything is fine as long as it's romance focused and about making the female lead happy. I'm really in love with the redo aspect, changing fate, and the personality change. There are a lot of novels with romance and male MCs, but it's hard to find and MC who can do it right.
You didn't specify if harem or not. Hmmmm. https://www.royalroad.com/fiction/10542/my-eyes-can-see (yuri) https://www.royalroad.com/fiction/19590/feralheart (harem but people say it's pretty good with max 6 wives because plot)
Forgot: A really fluffy one, FLUFFY and sweet that will makes you get diabetes: https://www.novelupdates.com/series/endo-and-kobayashis-live-commentary-on-the-villainess/ A villainess story. Prince x Villainess childhood friend tsundere / Gorilla Heroine (in the meaning of TOO OP) x Knight (that kept dying in near all the routes) / High school boy x HS petite energetic girl
https://www.scribblehub.com/series/19114/the-strongest-skill-becoming-rich-while-growing-strong/ A novel that is similar as Solo lvling / I alone lvl up. Looks like it will become harem. But slow release rate despite author having 100 chapters ready for patreon (gold digger maybe?).
I suppose u hv already read The Destruction of a Triad Boss Trilogy even tho I couldn't find it in ur reading list.
I'm fine with harem, just that it's really really hard to find good harem with good romance. I'm pretty sure you know the trouble and pitfalls of harem storytelling, interaction, drama, romance, and writing. That's why I usually avoid it when looking for romance. If you know any great ones, please please tell me. I find that the good part of harems is the variety of heroines, in that they have different personalities, backstories, events, and interactions. The various "First Meeting" or "How They Met" or "New Wiafu Intro" are always enjoyable. That's why I find the world hopping male MC romance brilliant because you get all of that without the actual harem part. Something new every world and you meet a new wiafu who is at the same time, the only and same wiafu.
https://www.novelupdates.com/series...-kiyoubinbode-subaya-sa-tayorina-tabi-o-suru/ It is light Isekai and should fit your requirements.
The bounty hunter (RR / harem) But it's a little dark, shithole isekai (that will become better later), enemies that are for some reason the good guys because they wanted to create a new Perfect World and the pretty girlfriend of MC's best friend (that was a cliche best friend fatty but became a pretty trap with a high pitch voice because of sickness) dies.
How about "Lonely Loser" and "Kou 2 time leap" they have both ln/wn translation i think edit: "My Pet Is a Holy Maiden ". its ln/wn
Mostly oneshots with very good romance(personal opinion) Gekkou Kuzu to Kinka no Qualidea Tabi ni Deyou, Horobiyuku Sekai no Hate Made Our Second Master(Found this very moving in-spite of the short amount of chapters)
https://www.novelupdates.com/series/i-am-a-big-villain/ Mc meet different personality female lead in each arc or world. All arc are so fluffy and heartwarming. Mc is devoted and loyal to female lead. It's 1v1
Some plot holes here and there but overall writing isnt bad and its readable https://www.royalroad.com/fiction/18219/my-sexy-childhood-friend-returned-and
